This pilot clinical trial studies radioembolization and ipilimumab in treating patients with uveal melanoma with liver metastases. Radioembolization kills tumor cells by blocking the blood flow to the tumor and keeping radioactive substances near the tumor. Monoclonal antibodies, such as ipilimumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving radioembolization together with ipilimumab may kill more tumor cells in patients with uveal melanoma
